Attached is a fie with an unusual extension, ORDER LIST.ace which is actually a compressed archive (basically a modified ZIP file). It contains an executable ORDER LIST.exe which has a VirusTotal detection rate of 15/56. That same VirusTotal report indicates traffic to:

booksam.tk/pony/gate.php

This is hosted on:

46.4.100.109 (Hetzner, Germany)

That IP address might be worth blocking. The Hybrid Analysis indicates that this steals FTP and perhaps other passwords. This is a Pony loader which will probably try to download additional malware, but it is not clear what that it might be.
